Webb, a prominent Democrat, and former Colorado Republican Gov. Bill Owens use the 30-second spot to slam Colorado for allegedly marketing edibles to kids, having the highest teen use of marijuana in the country and not giving money to Denver schools.

Neither Owens or Webb responded to a request for comment.

Mason Tvert says the former politicians are trying to re-write history.

Tvert worked on Amendment 64, which legalized recreational pot in Colorado, and he’s helping the supporters of Arizona’s Proposition 205.

“These are former Colorado leaders trying to make their own state look bad as a favor to politicians in other states,” Tvert said. “It’s particularly sleazy that they’re doing it in such a disingenuous fashion.”

Proposition 205 would legalize recreational marijuana in Arizona for people 21 years or older. And it would create a new state department to oversee growing, buying and selling pot.

Webb and Owens aren’t the only Colorado politicians voicing their opinions in Arizona.

Former Colorado Attorney General and current Colorado Springs Mayor John Suthers traveled to Phoenix in September to share the “dire consequences” of legalizing marijuana.

“People in law enforcement, people running a city, things like that, they’re going to see the neighborhood problems, they’re going to see the increase in DUIs, they’re going to see the school problems and things like that,” Suthers said during a press conference in Phoenix. “A lot of the average citizens are not going to see all that.”

There are significant differences between Colorado’s law and the one proposed in Arizona.

The Arizona law doesn’t allow cities to opt out of having dispensaries, and it doesn’t have a threshold for driving under the influence.

Suthers suggested Arizonans wait until Colorado’s law has been in effect for five years before deciding if it was a good idea.
